President Obama highlighted 3D printing in his State of the Union address last night, calling it the technology that "has the potential to revolutionize the way we make almost everything."

Obama pointed to a manufacturing innovation institute in Youngstown, Ohio that is already using the technology, and announced three more of these manufacturing hubs in his push to kickstart America's manufacturing engine. He urged Congress to fund 15 more such hubs around the country.

It's doubtful any of these hubs could show up in Silicon Valley. The president specified that these facilities should "turn regions left behind by globalization into global centers of high-tech jobs." And Silicon Valley definitely hasn't been left behind.

“I think in 10 to 15 years, literally Best Buy and stores like that will sell a version of a 3-D printer and our kits (providing a 3-D design) will go to an iTunes-like library” where users can download them and quickly print out their own products, said Rich Stump, principal at 3-D printing company Kemeera Inc., in a previous interview.
